If you do go back and climb, hire a certified guide, for one on one instruction, just a suggestion (I have done this a few times). I know little of rock climbing and when I get back into it I'm not going to power through it, but learn the right way the first time.
You can actually become a advocate for safe climbing, having been through this all and see that you can learn from this.
As for JK breaking your heart, thank goodness you had the moment to tell him later, and remember the ones that tell you do so because maybe they care, others would talk behind your back.
I am glad you were not hurt.
